Explanation:
Given parameters:
Distance of the seismic station from Blue mountain lake = 1200km
Unknown:
Time = ?
Solution:
To solve this problem, we must know that velocity is the displacement divide by time:
Velocity =
Since we are looking for time, lets make it the subject of the expression;
Time taken =
velocity of the wave is a consant = 6km/s
Time taken = = 200s

Answer:
With oil, gas, timber, diamonds, gold, coltan and bauxite, Africa is home to some of the largest deposits of natural resources in the world.

a joined transmitter and beneficiary called a transducer sends a sound heartbeat straight down into the water and the beat travels through the water and bouces off the sea base with the goal that the transducer can pickup the reflected sound
Answer:
One thing they COULD do is have the St.Louis and Houston Stations both send out very high wave frequencies and figure out from there what the magnitude is and send it back to LA, but that might take a bit of time, depening on if power cables aren't down.
